The natural process of things will tend to close gaps as the weather and humidity changes. As a rule, if the gap is less than the thickness of a dime, your flooring is normal and there’s nothing to worry about. If your gaps are more persistent, you might need to call in a professional to tighten up your hardwood floor so that they cease to be a problem. Denver Hardwood Floors

Eliminate any problem spots to make the subfloor level. Sand minor humps down with a hand-held or orbital sander to make the subfloor level. To fill any dips or low spots, use a leveling compound (also known as floor patch). Mix up the compound according to package directions, fill in the dips, then pull your straight piece of lumber back and forth over the spot to flatten and level it with the rest of the subfloor.[7] Denver Hardwood Floors

One of the best things about cork floors is that they are environmentally friendly because cork is a sustainable and renewable resource. The natural beauty of the material can suite any decor. The structure of the cork allows for a natural comfort and softness to absorb shock. This is why use of cork flooring is a good application in areas where people will be on their feet for extended periods of time. Using cork floors will reduce noise from traffic or dropping items, also because of the structure of the cork material. The natural properties of the material make it healthy because it is not only resistant to insects, but it is hypo-allergenic.
To fix a buckled floorboard, you need to be able to access the floor from below. The way to tackle this problem is to put weight on the buckled area from above — a cement block works well. Then install a 1 1/4-inch screw in the buckled flooring from below. Allow the screw to penetrate only halfway into the flooring, or it may come up through the finished surface. Driving the screw through the subfloor and into the flooring pulls the flooring down against the subfloor and gets rid of the buckled spot. Denver Hardwood Floors

Most floors use a tongue-and-groove design for connecting adjacent strips. This design makes replacing a single strip or plank challenging, but not impossible. First, look for any nails in the damaged board and drive them as far through the board as possible by using a hammer and nail set. Carpenters use nail sets to drive nails flush with trim without damaging the trim with a hammer. After you’ve cleared the nails, it’s time to remove the damaged board and install a new one.
